Retinal Vascular Conditions
The eye is like a camera with lenses in front and film in the back. The film is called the retina. The retina is nourished by small arteries that bring blood to the retina and veins that drain the blood away. If an artery becomes blocked or leaks, swelling or a "stroke" and visual damage can result. Similarly, if a vein is blocked, swelling and vision loss can occur. There are a variety of ways of dealing with many of these problems. For more information, see below.
